In the description of the present invention, it should also be noted that, unless explicitly specified and limited otherwise, the terms "mounted" and "connected" are to be construed broadly, and may be fixedly connected, detachably connected, integrally connected, directly connected, or indirectly connected, for example. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.
In order to better understand the present invention, a reaction vessel supply apparatus and a reaction vessel supply method according to embodiments of the present invention will be described in detail with reference to fig. 1 to 10.
Referring to fig. 1 to 3, the present invention provides a reaction vessel supplying apparatus, which includes a fixing frame 1, at least two conveying devices 2 and a controller (not shown).
The fixing frame 1 comprises at least two mounting plates 11, and at least two conveying devices 2 are respectively movably connected with the at least two mounting plates 11 in a one-to-one correspondence. Each of the conveying devices 2 includes a pair of guide plates 20 disposed opposite to each other, a supply passage 21 is formed between the pair of guide plates 20, and the conveying device 2 supplies a plurality of reaction containers C through the supply passage 21.
The conveying device 2 may be movably connected with the mounting plate 11 through a moving device, and the moving device may include, for example, a guide rail 111 and a slider 112 slidably connected with the guide rail 111, where the guide rail 111 is fixedly connected with the mounting plate 11, the conveying device 2 is fixedly connected with the slider 112, and an extending direction of the guide rail 111 is a moving direction of the conveying device 2. The conveying device 2 is movably arranged relative to the mounting plate 11, so that the conveying device 2 is conveniently pulled out of the fixing frame 1 to carry out overhaul, maintenance, loading of the reaction container C and the like, and then the conveying device 2 is pushed to the fixing frame 1.
In order to increase the stability of the fixing of the conveyor devices 2, two moving devices may be provided, which are spaced apart in the height direction of each conveyor device 2. In order to reduce the weight of the fixing frame 1 and improve the rigidity of the fixing frame 1, the mounting plate 11 can be partially hollowed out, and will not be described again. In addition, the number of the conveying devices 2 is at least two, one conveying device 2 is in the current working mode, and the rest conveying devices 2 are standby. The at least two conveying devices 2 are each movably connected to at least two mounting plates 11 in a one-to-one correspondence.
The controller is used for monitoring the running state of one conveying device 2 in the current working mode for supplying the reaction container C, and when the running state is abnormal, the current conveying device 2 is closed, and the other conveying device 2 in the at least two conveying devices 2 is started to continuously supply the reaction container C. The controller may be provided at any position, for example, fixed to the holder 1, or may be fixed to a position other than the reaction vessel supply device.
When the controller judges that the operation state of one of the conveying devices 2 currently in the operation mode is abnormal, the current conveying device 2 may be turned off and the other conveying device 2 may be started to continue supplying the reaction vessel C. The closed conveying device 2 can be pulled out from the fixing frame 1 to carry out maintenance work such as overhaul and the like, and the closed conveying device 2 is pushed into the original position after the maintenance is completed to serve as a standby conveying device 2. The whole maintenance process does not influence the normal operation of the other conveying device 2, so that the reaction container C can be continuously supplied, the time for stopping the machine to treat abnormal problems is reduced, and the working efficiency of the whole machine is improved.
Optionally, at least two mounting plates 11 of the fixing frame 1 are arranged in parallel, so that at least two conveying devices 2 are arranged side by side, and when the fixing frame is applied to a production line of sample analysis equipment, a manipulator can conveniently move to a supply channel 21 of any designated conveying device 2 along the same direction perpendicular to the side by side direction, a reaction container C is grasped, the movement path of the manipulator is simplified, and the detection efficiency of the sample analysis equipment is improved.
According to the reaction container supply device provided by the embodiment of the invention, by arranging at least two conveying devices 2 capable of being pushed and pulled to move, when one conveying device 2 supplies the reaction container abnormally, the other conveying device 2 can be replaced, so that the reaction container C can be continuously supplied, the time for stopping the machine to treat the abnormal problem is reduced, and the working efficiency of the whole machine is improved. In addition, the reaction vessel supply device has compact overall structure, saves space and is beneficial to being arranged in the assembly line detection and analysis equipment.
The specific structure of a reaction vessel supply apparatus according to an embodiment of the present invention is described in further detail below with reference to the accompanying drawings. For convenience of description, the embodiment of the present invention will be described by taking an example in which the reaction vessel supplying apparatus includes two transporting apparatuses 2.
Referring to fig. 1 and 4 together, the supply channel 21 of each conveyor 2 has a feeding position P1 and a discharging position P2 along its length, and the guide plate 20 is provided with a first sensor 201 corresponding to the discharging position P2 for sending a first signal to the controller when the reaction container C reaches the discharging position P2 and a second signal to the controller when the reaction container C is removed.
Alternatively, the first sensor 201 is a photosensor. The first signal indicates that the reaction container C has reached the discharging position P2, and at this time, the controller may control the conveying device 2to suspend conveying the reaction container C, so as to facilitate a manipulator or a manual removal of the reaction container C. The second signal indicates that the reaction vessel C at the discharge position P2 is empty, which means that the reaction vessel C has been removed, and the controller can control the conveying device 2to continue conveying the next reaction vessel C.
As an alternative embodiment, the controller is further configured to count the number of times the first signal is sent by the first sensor 201 of the conveying device 2 currently in the operation mode, and determine that the current operation state of the conveying device 2 is abnormal when the number of times the first signal is equal to the supply threshold value of the reaction container C.
The number of times the first signal is transmitted by the first sensor 201 is the number of reaction containers C that have been supplied to the discharging position P2. The supply threshold of the reaction containers C refers to a threshold of the number of the reaction containers C that have been supplied in place, which may be, for example, 99.5% of the total number. For example, if the total number of reaction containers C that the conveying device 2 can supply is 1000, the supply threshold is 995. When the number of times of the first signal transmitted from the first sensor 201 is equal to the supply threshold value of the reaction container C, the controller determines that the current operation state of the conveyor device 2 is abnormal, and needs to switch to another conveyor device 2 and reload the reaction container C for that conveyor device 2.
As an alternative embodiment, the controller is further configured to determine that the current operation state of the conveying device 2 is abnormal when the first signal or the second signal sent by the first sensor 201 of the conveying device 2 currently in the operation mode is not received within a predetermined time.
If the controller does not receive the first signal or the second signal within the predetermined time, for example, the predetermined time is 1s, which indicates that the reaction vessel C may be jammed due to a failure of the conveying device 2, the controller determines that the current operation state of the conveying device 2 is abnormal, and needs to switch to another conveying device 2, and eliminates a failure problem of the conveying device 2.
As described above, when the controller determines that the current operation state of the conveyor 2 is abnormal, the conveyor 2 needs to be pulled out from the holder 1 along the moving device for maintenance, and the conveyor 2 is pushed to the holder 1 after the maintenance is completed. At this time, it is necessary to ensure that the conveying device 2 is pushed to the original position, so that a safety accident is avoided when the conveying device 2 is started.
Specifically, the fixing frame 1 further includes a bottom plate 12, the bottom plate 12 is used for supporting at least two conveying devices 2, a first magnetic member 121 is disposed at one end of the bottom plate 12 corresponding to the supply channel 21, a second magnetic member 203 and a second sensor 202 are disposed on the guide plate 20, after the conveying devices 2 move to a predetermined position along the mounting plate 11, the first magnetic member 121 and the second magnetic member 203 are adsorbed together, and the second sensor 202 is triggered to send a third signal to the controller.
Alternatively, the first magnetic member 121 is a magnet, the second magnetic member 203 is a metal member having magnetic attraction property, such as an iron plate, a nickel plate or an iron-nickel alloy plate, and the outer surface is coated with an anti-corrosion coating. Alternatively, the second magnetic member 203 may be an electrolytic lead-zinc-plated sheet, i.e., a zinc-plated layer on the surface of a cold-rolled sheet. Optionally, the second sensor 202 is a micro switch, and the micro switch is a switch triggered by physical and mechanical, so that the micro switch is not interfered by the attribute of the triggering object, and the problem of detection misjudgment caused by the traditional photoelectric sensor can be effectively solved. The second magnetic member 203 and the second sensor 202 are located in the same plane, and when the first magnetic member 121 and the second magnetic member 203 are attracted together, the conveying device 2 is illustrated to move to a predetermined position along the mounting plate 11, and at this time, the first magnetic member 121 can just touch the second sensor 202, so that the second sensor 202 is triggered to send a third signal to the controller. The third signal indicates that the conveyor 2 has moved to a predetermined position along the mounting plate 11 and can be switched to the operating mode at any time.
In addition, as shown in fig. 3, magnetic beads O are preset in the reaction container C for subsequent mixing of the sample with the functional modules such as reaction reagent and magnetic bead detection. In order to prevent the first magnetic member 121 from magnetizing the magnetic beads O in the reaction vessel C, affecting the magnetic bead detection result, the height difference between the first magnetic member 121 and the reaction vessel C needs to satisfy a preset distance. The predetermined distance is related to the magnitude of the magnetic force of the first magnetic member 121, depending on the specific application.
Due to machining errors of parts such as the mounting plate 11 or assembly errors of the parts with the guide rail 111 and the sliding block 112, the conveying device 2 may shift in the direction in which at least two conveying devices 2 are arranged side by side, so that the conveying devices 2 wear during operation, which is unfavorable for the conveying precision of the conveying devices 2 for supplying the reaction containers C.
To solve this problem, the end of the bottom plate 12 corresponding to the supply passage 21 is further provided with a fixing member 122, the fixing member 122 is provided with a positioning pin 123, the guide plate member 20 is correspondingly provided with a pin hole 204 which is engaged with the positioning pin 123, and the positioning pin 123 extends into the pin hole 204 after the conveying device 2 moves to a predetermined position along the mounting plate 11. By the engagement of the positioning pin 123 with the pin hole 204, the conveying device 2 can be positioned quickly. At the same time, the continuous magnetic attraction force generated between the first magnetic member 121 and the second magnetic member 203 can ensure that the conveying device 2 does not move in the side-by-side direction, and further improves the conveying precision of the conveying device 2 for supplying the reaction containers C.
Referring to fig. 5 to 7, each conveyor 2 includes a support plate 22, a turntable 23, a conveyor belt 24, and a wheel assembly 25.
The support plate 22 is movably coupled to the mounting plate 11, and a pair of guide plates 20 are fixedly coupled to the support plate 22. Specifically, the support plate 22 is connected to the slider 112 of the aforementioned moving device, so as to realize movable connection of the support plate 22 to the mounting plate 11. The support plate 22 further includes a bent portion 223 parallel to the bottom plate 12, and a pair of guide plates 20 are disposed at the bent portion 223 to form the supply passage 21.
The turntable 23 is rotatably connected with the support plate 22, and the turntable 23 includes a rotating shaft 231 and a pair of disk bodies 232 coaxially connected with the rotating shaft 231 and arranged at intervals.
One end of the conveyor belt 24 is wound on the rotating shaft 231 between the pair of disc bodies 232, the conveyor belt 24 is provided with a plurality of reaction containers C which are sequentially arranged along the length direction of the conveyor belt 24, and the reaction containers C are positioned on one side of the conveyor belt 24 away from the rotating shaft 231.
The rotating wheel assembly 25 is connected to the support plate 22, the rotating wheel assembly 25 is disposed between the turntable 23 and the guide plate 20, and the other end of the conveyor belt 24 is wound around the rotating wheel assembly 25 for guiding the reaction containers C on the conveyor belt 24 to the supply passage 21.
Further, the wheel assembly 25 includes a drive motor 251, a drive wheel 252, a first guide wheel 253, and a second guide wheel 254.

The driving wheel 252 is coaxially connected with the output shaft of the driving motor 251, an annular groove 252a is arranged on the driving wheel 252, and the other end of the conveyor belt 24 is wound on the annular groove 252 a. Specifically, the driving motor 251 and the driving wheel 252 are respectively disposed on two sides of the supporting plate 22, so as to drive the driving wheel 252 to drive the conveyor belt 24 to rotate.
The first guide wheel 253 and the second guide wheel 254 are respectively positioned between the turntable 23 and the driving pulley 252 and are in frictional contact with the conveyor belt 24, the first guide wheel 253 is positioned close to the turntable 23 for guiding the conveyor belt 24 into the supply channel 21, and the second guide wheel 254 is positioned on one side of the first guide wheel 253 away from the turntable 23 and above the supply channel 21 for separating the reaction containers C from the conveyor belt 24.

Wherein the reaction vessel C is separated from the conveyor belt 24 as the conveyor belt 24 passes the second guide wheel 254, and thus falls into the supply passage 21 under the second guide wheel 254. The separation of the reaction vessel C from the conveyor belt 24 is related to the arrangement of the components of the rotor assembly 25 and the structure of the feed channel 21.
In one aspect, as shown in fig. 5, a first central line between the central axis of the first guide wheel 253 and the central axis of the second guide wheel 254 is L1, a second central line between the central axis of the second guide wheel 254 and the central axis of the driving wheel 252 is L2, and an included angle θ between the first central line L1 and the second central line is equal to or greater than 90 °.
Since the included angle θ between the first central line L1 and the second central line L2 is greater than or equal to 90 °, when the conveyor belt 24 is guided into the supply channel 21 by the first guide wheel 253 and is in frictional contact with the second guide wheel 254, the reaction container C shown at the far right in fig. 5 has a tendency to separate from the conveyor belt 24 moving upward under the action of its own gravity.

When the conveyor belt 24 is guided into the supply channel 21, it moves toward the driving wheel 252 under the guiding action of the second guiding wheel 254, so as to drive the reaction container C to move upward, while the ears E of the reaction container C are blocked by the grooves 205 provided in the pair of guiding plates 20, and the conveyor belt 24 continues to move upward toward the driving wheel 252 through the grooves 205, while the reaction container C moves downward under the action of its own gravity, so that the conveyor belt 24 is separated from the reaction container C, and the reaction container C falls into the supply channel 21.
Referring to fig. 4 and 7-9, the reactor supply apparatus further includes a cover assembly 3, the cover assembly 3 includes a cover plate 31 and an extension portion 32, the cover plate 31 covers the supply channel 21 between the second guide wheel 254 and the discharging position P2, the extension portion 32 is disposed on a side of the cover plate 31 facing the supply channel 21, and the extension portion 32 is telescopically inserted into the supply channel 21 under the second guide wheel 254.
As shown in fig. 8 and 9, the cap assembly 3 further includes a toggle 33 and a hinge 34, and the cover plate 31 is pivotally connected to the guide plate 20 by the hinge 34 to open or close the supply passage 21. The toggle member 33 is disposed on a side of the cover plate 31 facing away from the supply passage 21 and is connected to the protruding portion 32. One end of the extension 32 is telescopically inserted between the second guide wheel 254 and the reaction vessel C in the supply passage 21, the other end is provided with a cylinder, a spring (not shown in the drawing) is sleeved outside the cylinder, and the cover plate 31 is correspondingly provided with a hole matched with the cylinder and the spring, so that the extension 32 can telescopically move relative to the cover plate 31. When the toggle member 33 is moved in the arrow direction in fig. 8, the protruding portion 32 can be inserted into the supply passage 21 under the second guide wheel 254. When the toggle member 33 is moved in a direction opposite to the arrow direction in fig. 8, the protruding portion 32 is withdrawn from the supply passage 21 under the second guide wheel 254, so that the cover plate 31 can be turned around the hinge 34 to open the supply passage 21.
As shown in fig. 7, the reaction container C is pre-provided with magnetic beads O therein, and when the conveyor belt 24 is separated from the reaction container C, the opening H of the reaction container C is opened, the reaction container C moves downward to fall into the supply passage 21, and the magnetic beads O tend to escape toward the opening H of the reaction container C due to inertia. By moving the toggle member 33 to the left, the projecting portion 32 can be inserted into the supply passage 21 below the second guide wheel 254 and covered with the opening H of the reaction container C just separated from the conveyor belt 24, so that the magnetic beads O can be prevented from escaping from the opening H. In addition, the cover plate 31 covers the supply channel 21 between the second guide wheel 254 and the discharging position P2, so as to prevent impurities such as dust from falling into the reaction container C, thereby avoiding affecting the cleanliness of the subsequent sample and the accuracy of the sample analysis result.
When most of the conveyor belt 24 wound around the rotating shaft 231 of the turntable 23 is wound around the annular groove 252a of the driving pulley 252 and the conveyor belt 24 is in a tensioned state, the conveyor belt 24 cannot drive the reaction containers C to move toward the feeding channel 21, the controller recognizes that the operation state of the conveying device 2 is abnormal, and controls the driving motor 251 to stop rotating, and at this time, a small amount of reaction containers C fall into the feeding channel 21 and cannot move to the discharging position P2. The conveying device 2 is moved out of the fixing frame 1, the toggle piece 33 is moved to the right, then the cover plate 31 is turned around the pivot of the hinge 34, so that a small amount of reaction containers C falling into the supply channel 21 can be manually taken out, and the counting of the reaction containers C arranged on the new conveying belt 24 is prevented from being influenced.
If the counting of the reaction containers C does not need to be considered, the controller does not receive the first signal or the second signal sent by the first sensor 201 of the conveying device 2 currently in the working mode within a predetermined time to determine the running state of the current conveying device 2, a small number of reaction containers C may also be manually moved to a suitable position, for example, the reaction container C in the front of the queue is moved to the discharging position P2, and the remaining reaction containers C are sequentially arranged, so that the movement of the new conveyor belt 24 is not affected, and the waste of the reaction containers C is avoided. Then, the cover plate 31 is turned around the hinge 34, the cover plate 31 is covered on the supply channel 21, the toggle piece 33 is moved to the left, the new conveyor belt 24 is reloaded between the rotating shaft 231 of the rotating disc 23 and the rotating wheel assembly 25, and the conveying device 2 is moved to the original position of the fixing frame 1 to serve as a standby conveying device.
Referring to fig. 6 again, a supporting plate 22 of the conveying device 2 is provided with a boss 221 and a lock pin 222 rotatably connected with the boss 221 corresponding to a rotating shaft 231 of the turntable 23, the rotating shaft 231 is sleeved on the outer periphery side of the boss 221 and is pressed on one of the discs 232 through the lock pin 222, and an elastic member 26 is arranged between the other disc 232 and the supporting plate 22.
Alternatively, the elastic member 26 is an O-ring rubber. Because the arm of force of the locking pin 222 pressing the disc 232 is short, the disc 232 is not easily pressed. The elastic piece 26 is arranged between the tray 232 and the support plate 22, so that friction force generated by extrusion between the tray 232 and the support plate 22 can be increased, and the anti-loosening purpose is achieved.
Referring to fig. 10, an embodiment of the present invention further provides a reaction vessel supply method of the reaction vessel supply apparatus as described above, including:
Step S1, acquiring the running state information of the conveying device 2 in the current working mode for supplying the reaction vessel C;
Step S2, when the running state information is abnormal, sending a stop signal to the current conveying device 2;
step S3, starting the other conveying device 2 of the at least two conveying devices 2 to continue to supply the reaction vessel C.
As described above, when the controller determines that the current operation state of the conveyor device 2 is abnormal, there is a possibility that the remaining amount of the reaction container C is insufficient, or that the current conveyor device 2 is out of order, and the conveyor device 2 needs to be pulled out of the holder 1 along the moving device to perform maintenance, for example, the reaction container C is reloaded into the conveyor device 2, the problem of the failure of the conveyor device 2 is eliminated, and the conveyor device 2 is pushed to the original position of the holder 1 after the maintenance is completed. The maintenance process does not affect the normal operation of other conveying devices 2, so that the reaction container C can be continuously supplied, the time for stopping the machine to treat abnormal problems is reduced, and the working efficiency of the whole machine is improved.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict.
